4.2.0 INTRODUCTION

This section of the CMT manual is a user’s manual for the software of both the NMC Pro and the NMC Junior. It is written as though the NMC Pro is the product software being used. The NMC Junior uses the same software format as the NMC Pro; however the software is constrained by the limitations of the NMC Junior’s hardware. Where the NMC Junior differs, these limitations or differences are explained in a ‘JR’ box as follows beneath.

This box explains the differences or limitations of the NMC Junior as they occur in the manual.

Netafim's NMC Pro is a top of the line irrigation controller with the most updated technology. It manages irrigation, fertigation, misting and cooling systems. This section of the CMT Manual describes the NMC Pro programming and operating procedures. Prior to using the controller in your facility, you will need to complete the controller’s hardware installation (see section 2.2 Installation – Hardware – NMC 64/Pro as well as its software installation (see section 3.2 Installation – Software – NMC Irrigation).

Once the controller is installed, configured, set-up and tested, all relevant menus will be available for use. All values indicated in this manual are in SI (metric) units.

In everyday use, the user of the controller will only use the first four icons of the main screen (Icons 1 to 4). However, prior to using them, the installation of the software must be complete. This software installation is handled using the second set of 4 icons (Icons 5 to 8).

This section of the CMT Manual only deals with Icons 1 – 4. (See section 3.2 Installation – Software – NMC Irrigation for Icons 5 - 8).

o Dosing channels (left column) – Dosing channels setup for system. o Open(%) – Actual opening percentage of the dosing channel. o Min(%) - Minimum allowed opening percentage of the channel. o Prg(%) – Calculated opening percentage of the channel. o Max(%) – Maximum allowed opening percentage of the channel.

The Prg (%) and Min/Max (%) are calculated according to the 1.3 DOSING program settings, dosing channel flow rate + allowed deviation [High(%) and Low(%)] set in 7.6 DOSING CHANNEL CONFIGURATION] and actual (measured) water flow. When EC/pH control is active the Open (%) will change according to the difference between the set and the actual EC/pH values. If the Open(%) is close to the Min(%) or Max (%) it means that there is a big deviation between the dosing program settings to the actual injection ratio. The Open (%) cannot be higher than the Max (%) and cannot be lower than the Min(%). If it is identical to one of them, the NMC Pro Controller will not be able to reach the set EC/pH values and the dosing program settings must be rechecked. See Section 5.5 The Bucket Test.

4.2.0.9 RESETTING NMC PRO CONTROLLER In the unlikely event that the controller software for example “freezes” or a software setting change is not implemented, the controller could require a reset. The NMC Pro Controller can be reset by:

• 1) Warm Reset or • 2) Cold Start.

4.2.0.9.1 WARM RESET

• During a Warm Reset the controller CPU is restarted. The program and configuration settings will not be lost.

• It is recommended to perform this procedure before doing a Cold Start. • To perform a Warm Reset, stop all active irrigation processes and then depress the reset

button on the CPU. The reset button can be released when no text is displayed on the controller screen. (See FIGURE 18 for the NMC Pro and FIGURE 19 for the NMC Junior)

• After Warm Reset procedure has ended the NMC Pro will return to the MAIN screen.

FIGURE 18. NMC PRO - WARM RESET

Warm reset button


FIGURE 19. NMC JUNIOR - WARM RESET

Warm reset button. This button is underneath a steel protective cover. The cover is not shown in this diagram. The reset button can be accessed without removing the cover. 4.2.0.9.2 COLD START

• Cold Start resets the NMC Pro to the original factory settings. This procedure should be performed:

o After upgrading the controller software version o When reinstalling the controller o After adding input or output cards o When instructed by a Netafim technician

All program and configuration settings will be lost, it is therefore recommended to perform a back-up to the Data Plug before starting this procedure. See section 6.9 WRITE TO DATA PLUG for instructions on performing the back-up and section 6.10 READ FROM DATA PLUG to restore controller settings.

NB


• To perform a cold start:

o Disconnect the NMC Pro power supply. o Turn power on while depressing the DELETE key until the COLD START pop-up screen

appears. If you choose “NO”, the NMC Pro will continue to its usual power-up

procedure and the settings will remain untouched. If you choose “YES”, NMC Pro will perform the cold start procedure and the

controller will start with RAM and EPROM cleaning procedure. All controller settings will be erased and restored back to default factory settings. All history will be erased.

o After the cold start procedure has ended, the NMC Pro will return to the MAIN screen.

4.2.0.10 ANALOGUE INPUTS Analogue inputs are received from an analogue sensor as either a voltage or a current. However a computer cannot read such a value without it being converted to a digital number. The analogue inputs in several of the NMC software’s screens such as ‘Status’ and ‘Test’ screens are displayed in values which are labelled as ‘A/D’. ‘A/D’ = Analogue-to-digital converter This simply means analogue-to-digital converter and the values displayed in these screens are numbers that can be read by a computer: in this case the NMC Controller. The numbers themselves have no unit of measurement. They are more like a code, which the controller is pre-programmed to read.

• DATE – Displays current date. • TIME – Displays current time. • IRRIGATION PROGRAM

o Program [Value in range 1 to 15] – Select a program by entering the program number and confirm by pressing ENTER.

o Priority [Value in range 0 to 15] - Priority determines the order in which program starts will take place. If start time is the same, higher priority programs come first. Higher priority programs do not stop currently operative programs. If start time and priority are the same, irrigation programs with a lower number are executed first. Priority ranges are between 0 and 15, 15 being the highest.

o Constant / Daily / Condition / Radiation Sum


Constant [Value in range -100% to 999%] – Increase or decrease the irrigation run time/quantity for all valves included in this program. 0% means the time/quantity will be as specified in the 1.2 WATER RUN TIME program, 100% will be twice the time/quantity and –50% will be half the time/quantity specified in the 1.2 WATER RUN TIME program. To decrease enter the required percentage of change, press the +/- key and then confirm with the ENTER key. The percentage of change will be active until you specify otherwise.

Daily [Value in range -100% to 999%] – Increase or decrease the irrigation run time/quantity for all valves included in this program. 0% means the time/quantity will be as specified in the 1.2 WATER RUN TIME program, 100% will be twice the time/quantity and –50% will be half the time/quantity specified in the 1.2 WATER RUN TIME program. To decrease enter the required percentage of change, press the +/- key and then confirm with the ENTER key. The percentage of change will be active only for the present day.

Constant % and Daily % do not change time/quantity of water before and after settings, nor dosing quantities. When setting watering program and using Spread the percentage affects not only the water but also the dosing.

Condition [Value in range 0 to 15] – Specify whether the condition program

can start/stop irrigations, and choose a condition program number to start/stop irrigations. Irrigations will be started and stopped according to the settings of the relevant condition program (see 1.4 EXTERNAL CONDITION program for additional information).

If irrigation is not triggered due to the relevant condition program and the maximum time (see Maximum Time below) has lapsed, irrigation will be performed. When choosing condition, the screen will be split in two. To view the cycle sequence, press the down arrow when the cursor is placed on the bottom of the screen. The condition program has the third priority after active irrigation and uncompleted irrigation.

It is not possible to set the same Condition program for two different programs.

Radiation Sum / VPD Sum – Select option if irrigations can be triggered by

the radiation sum / VPD sum. The specific radiation sum limit / VPD sum limit used to trigger irrigation are specified per period (see Radiation Sum Limit / VPD Sum Limit below).

If irrigation is not triggered due to the relevant Radiation Sum Limit / VPD Limit and the maximum time (see Maximum Time below) has elapsed irrigation will be performed. When choosing Radiation Sum, the screen will be split in two. To view the cycle sequence, press the Down arrow when the cursor is placed on the bottom of the screen.

*Radiation / VPD sums are not available in the NMC Junior.

NB

NB

JR


o Start time [Value in range 00:01 to 23:59] - ENTER up to 6 start times (periods) per

day for each program. Setting start time as 00:00 means program is off. o Clock Start [Value in range 0 to 99] - Set the number of irrigation cycles that must be

performed in this period. For Constant and Daily the first cycle will start at the specified start time, subsequent cycles will start after the specified delay time set (see Minimum Time below).

In the NMC Junior, this feature is called ‘Cycles’. Set the number of irrigation cycles for each period. The first cycle starts at the specified start time. Subsequent cycles will start after the specified ‘Delay’ time in the row underneath.

o Condition Starts [Value in range ON or OFF]

On – Irrigations can be triggered by the 1.4 EXTERNAL CONDITION program if the specified condition program settings are met (condition program active).

Off – Irrigations will not be triggered by the 1.4 EXTERNAL CONDITION program regardless of the condition program status.

o Radiation Sum Limit. [Value in range 0 to 9999] – Specify the radiation sum limit at which irrigation will take place. The radiation sum counter of the specific program is automatically reset when irrigation is performed. If radiation sum limit is “0” it is ignored.

o VPD Sum Limit. [Value in range 0 to 9999] – Specify the VPD sum limit (kPa.min) at which irrigation will take place. The radiation sum counter of the specific program is automatically reset when irrigation is performed. Irrigation based on VPD sum occurs only during the VPD time frame set in Sub-menu 6.1. See Section 3.2.6.1 Installation – Software – Irrigation.

o Minimum Time [Value in range 00:00 to 23:59] – For time based irrigation the minimum time (delay time) between cycles is counted from start of previous cycle to start of next cycle. For condition and radiation sum modes this setting is used to determine the minimum time allowed between irrigations. If the condition program becomes active or the radiation sum limit has been reached, irrigation will not be performed until this time has elapsed.

o Maximum Time [Value in range 00:00 to 23:59] – The maximum time between two subsequent cycles. This value is used to limit the time between two cycles when using dynamic irrigation triggers such as condition program or radiation sum limit. When the specified maximum time from the start of the previous cycle has elapsed, irrigation will take place regardless of the condition program status or radiation sum value.

In the NMC Junior, the minimum and maximum times are replaced by ‘Delay’: the time between the start of a cycle and the start of the next cycle. For example, if the set ‘Run Time’ is 30 minutes and the ‘Delay’ is 45 minutes, the second cycle will start 15 minutes after the end of the first cycle.

o Valve # [Value in range 0 to 255] - The NMC Pro can operate valves in any required order. Set the valve number and press ENTER.

The following window will appear:

Select “blank” and press ENTER to set the valve to operate alone, or select “+” (plus) to operate together with the next valve. Several valves can be set to work together as a group. A valve group will have the same 1.2 WATER RUN TIME program and the same 1.3 Dosing program (the 1.2 WATER RUN TIME and/or 1.3 DOSING program numbers set for the valve to the far left of the group will be used). Each irrigation program can include a maximum of 40 valves (columns) in any required order (all of them set to work together, one after the other, a few groups, etc.). The same valve can be entered several times with different settings.

In this window in the NMC Junior, ‘blank’ is replaced with a minus ‘-‘.

o Run Time # [Value in range 0 to 60] – ENTER a 1.2 WATER RUN TIME program

number for a valve or a group of valves. When setting valves to work individually a 1.2 WATER RUN TIME program should be set for each valve. When setting a group of valves to work together (“+” mark between them) a 1.2 WATER RUN TIME program should only be set for the valve to the far left of the group, the rest of the valves will follow this setting. The quantity set in the 1.2 WATER RUN TIME program for a valve group will be the quantity given for all valves set to operate together not per valve (also see 1.2 WATER RUN TIME program).

o Dosing Program [Value in range 0 to 10] – ENTER a 1.3 DOSING program number for a valve or a group of valves. When setting valves to work individually a 1.3 DOSING program should be set for each valve. When setting a group of valves to work together (“+” mark between them) a 1.3 DOSING program should only be set for the valve to the far left of the group, the rest of the valves will follow this setting (also see 1.3 DOSING program).

o Day: (xx/xx) [Value in range 1 to 14] – Cycle days, set the right hand side value (number of cycle days) first see below: (xx/xx) - The left hand side setting defines the current day in the cycle. The

standard setting for current day when using cycle days to irrigate according to days of the week is to set Monday as day 01.

(xx/xx) - The right hand side setting defines the number of cycle days to use per program.

( x x x ……) – The complete cycle (number of days set) will be displayed to the right hand side of the screen. The current day in the cycle will be highlighted.

JR


o Dose / Water [Value in range Dose, Water or None]: By moving the curser with the arrow keys to the relevant cycle day and

pressing ENTER the following screen will be displayed:

Set the action to be taken for each cycle day by selecting Dose, Water or None and press ENTER. “Dose” means fertigation (water + dosing), “Water” means irrigation without dosing and “None” means the program is idle in that day.

The dosing operates according to Dose or Water for the present day and not according to the setting when the irrigation has started. If an irrigation starts at 18:00 and on this day dosing is set (“D”) when the irrigation crosses midnight to a day where no dosing is set (“W”) dosing stops at midnight.

With an Irrigation Program that includes 1.3 DOSING program numbers for valves, dosing will always start if the program is started manually. To stop dosing for manual irrigation program start, change the dosing rate set in 1.3 DOSING program quantities to 0.

Setting irrigation that is longer than 24 hours If the number of cycle days is set as 1 and the water run time is over 24 hours, the irrigation will repeat itself continuously, which means continuous irrigation.

4.2.1.1.4 EXAMPLE: IRRIGATION BASED ON VAPOUR PRESSURE DEFICIT (VPD) SUM Irrigation starts based on VPD sum are done according to the accumulation of units of VPD multiplied by time and measured in kilopascal-minutes (kPa·min). VPD Vapour pressure deficit is the difference in vapour pressure measured in kPa between saturated air (100% relative humidity, inside the stomata of the plant leaves) and the actual air vapour pressure (less than 100% humidity, away from the plant leaves). EQUATION 1. VPD

VP saturation (kPa) Less VP air (kPa) = VPD (kPa)

These theoretical vapour pressures can be estimated by measuring the air temperature and the relative humidity. The NMC Pro software calculates the VPD using readings from a temperate sensor and a relative humidity sensor. VPD Sum The irrigation interval between irrigation starts is set according to a chosen VPD sum, which multiplies the VPD in kPa by time in minutes. EQUATION 2. VPD SUM

VPD sum (kPa·min) = VDP (kPa) x accumulated time (minutes) The VPD sum at which to irrigate is chosen by the irrigation operator. The NMC software allows the operator to select different VPD sums for different periods of the day.

FIGURE 32. IRRIGATION BASED ON VPD SUM

Program 5 will be used to control valve numbers 1 and 2 by VPD sum limit. In addition to control by radiation sum limit, 1 irrigation cycle is required to at 05:30 to start the day’s irrigation. After 19:00 no more irrigation cycles are required.

Between 06:00 to 10:00 and 16:00 to 19:00 the VPD sum level to start

irrigation is 120 kPa·min. Irrigation required every 40 mins to 2 hours.

DOSING PROGRAM • Program [Value in range 1 to 10] – Select a program by entering the program number and

confirm by pressing ENTER. • EC Pre-Control [Value in range OFF or ON]:

o Off – EC pre-control is not active for this dosing program. If the hydraulic system includes an EC pre-control system the valve will be shifted towards the fresh water source.

o On – EC pre-control is active for this dosing program.

The NMC Junior facilitates 8 dosing channels and only 6 dosing meters. EC Pre-control is not featured.

INJECTION PER DOSING CHANNEL

• Dosing channel number – 1 to 8. • Reaction – A read only line indicating the injection method for the dosing channel (dosing

channel reaction is set in screen 7.6 DOSING CHANNEL CONFIGURATION): o EC – Dosing through this channel will be controlled by measured EC level. o Acid – This channel is used for high pH level correction. Dosing through this channel

will be controlled by measured pH level. o Passive – Dosing through this channel do not respond to changes in measured EC or

pH levels. This channel will be controlled as set in the dosing program regardless of the EC or pH values.

JR


o Alkali – This channel is used for low pH level correction. Dosing through this channel will be controlled by measured pH level.

• Dosing channel volume [Value in range 0 to 9999.99 or 0 to 99:59] – Set the quantity / time to be injected for each dosing channel. The injection volume (proportional quantity, proportional time, time and quantity, see dosing injection method below) can be set separately for each reaction (method) of injection (EC, Acid, Passive, Alkali).

• Target EC [Value in range 0 to 10] – Set the required EC target value. This line will be visible if EC Control or EC Alarms are set to YES in screen 7.7 DOSING CONFIGURATION.

• Target pH [Value in range 0 to 14] – Set the required pH target value. This line will be visible if pH Control or pH Alarms are set to YES in screen 7.7 DOSING CONFIGURATION.

• Target EC Pre-Control [Value in range 0 to 10] – Set the required EC pre-control target value. This line will be visible if EC-Pre Control is set to ON, see EC-Pre Control above.

• Passive Dosing Method [Value in range P.QTY, P.TIME, TIME or QTY.] – Set the required injection method for the passive dosing channels (see Dosing injection method below).

• EC Dosing Method [Value in range P.QTY, P.TIME, TIME or QTY.] – Set the required injection method for the EC dosing channels (see Dosing injection method below).

• pH Dosing Method [Value in range P.QTY, P.TIME, TIME or QTY.] – Set the required injection method for the pH dosing channels (see Dosing injection method below).

DOSING INJECTION METHOD

• Proportional Quantity (liters/m³) – Liters of fertilizer to inject per cubic meter (1000L) of irrigation water. Each dosing channel can be set to give a different amount.

o For example: If dosing channel is set to P.QTY of 5.0 ℓ/m³ and set water quantity is 15.0 m³/h then the total quantity of fertilizer that will be given is 5.0 ℓ/m³ x 15.0 m³/h =

75 litres. • Proportional Time (hh:mm) - The time to fertilize will be spread equally within the given

irrigation time. Each dosing channel can be set to give a different amount. o For example:

Dosing channel 1 is set to 00:10 and dosing channel 2 is set to 01:00 Set irrigation water time is 3 hours. The NMC Pro will proportionally divide (spread) the set dosing time for each

dosing channel across the set irrigation time. Dosing channel 1 will be on for a total time of 10 minutes and dosing channel 2 will be on for a total time of 60 minutes during the 3 hours of irrigation.

• Time (hh:mm) – The time for dosing is entered for each dosing channel. Dosing will be done in one bulk that will start after water before time or quantity has elapsed as set in 1.2 WATER RUN TIME.

• Quantity (litres) - The quantity for dosing is entered for each dosing channel. Dosing will be done in one BULK or SPREAD throughout the irrigation depending on the setting in 7.7 DOSING CONFIGURATION for the line Dosing by QTY.Method. Dosing will start after water before time or quantity has elapsed as set in 1.2 WATER RUN TIME.


Example: Dosing Program based on Proportional Quantity (Open Field) It is required from the fertigation program to inject 2.4 litres/m³ from Tank A (Dosing Channel 1) and 0.8 litres/m³ from Tank B (Dosing Channel 2). It is also required to receive alarms if the measured EC level deviates from the set level of 1.2 EC, pH correction is not required. Dosing program 1 will be used for this recipe:

• # [Value in range 1 to 15] – External condition program number. • From [Value in range 00:01 to 23:59] – Set the start time of the condition program time

frame. • To [Value in range 00:01 to 23:59] – Set the end time of the condition program time frame.

The condition program will only be operational in the defined time window (between start “From” to end “To” times). Each condition program can be operational on different hours. A closed contact will be regarded as an active contact.

NB


• Start Dry Contact [Value in range NONE or 1 to 16] – Set the dry contact number for activating the condition program.

• Trigger Type [Value in range One Shot, Multi Shot or Only If On] – Choose one of three trigger types:

o One Shot – If the start dry contact is closed for more than 6 seconds the associated condition program will be started. The contact must open and close to initiate the condition program. The run time for an irrigation program connected through this trigger will be according the water run time setup for this irrigation program.

o Multi shot – If the start dry contact is closed for more than 6 seconds the associated condition program will be started. If the contact is still closed when the irrigation water run time has elapsed, the condition program will remain active and another irrigation cycle will be initiated. The start dry contact do not have to open and close in order to keep condition program active, it only needs to be closed when the irrigation water run time elapses. The minimum run time for an irrigation program connected through this trigger will be according the water run time setup for this irrigation program.

o Only If On - If the start dry contact is closed for more than 6 seconds the associated condition program will be started. The condition program will remain active as long as the dry contact is closed.


FIGURE 48. EXAMPLES OF RUN TIMES FROM EXTERNAL CONDITIONS

• Stop Dry Contact [Value in range NONE or 1 to 16] – Set the dry contact number for deactivating the condition program. Since the stop dry contact has a higher priority than the start dry contact, the associated condition program will not be activated as long as the stop dry contact is closed.

If the time between flushing is set to 01:00 it means that a flushing cycle will be activated after 1 hour of irrigation regardless of delta pressure switch status. If set to zero (--:--), flushing will only take place if triggered by a delta pressure switch.

• Flushing Time [Value in range 00:00 or 99:59] – Activated time of each filter back flush valve. • Delay Between Filters [Value in range 00:00 or 99:59] - The delay time between one filter

back flush valve closing to the next filter back flush valve opening. This time is usually used to allow pressure build up.

• Delta Pressure [Value in range NO or YES] – Define whether filter back flushing can be triggered by a digital delta pressure switch.

• Delta Pressure Value [Value in range 0 to 10bar] – Define the delta pressure of the inlet pressure sensor (Pin) and outlet pressure sensor (Pout) at which filter back flushing will be triggered (Only relevant when the application consists of analogue Pin and Pout sensors).

• Delay Delta Pressure [Value in range 00:00 or 99:59] – Define the time that the delta pressure (digital or value) must be relevant before a filter back flushing cycle will be triggered. This time is used to prevent unnecessary back flushing cycles from taking place.

• Delta Pressure Reiteration [Value in range 0 to 99] – Number of consecutive filter back flushing cycles triggered by the delta pressure that can take place. When this number of consecutive cycles are reached the NMC Pro will generate an alarm indicating that the delta pressure sensor is defective. The NMC Pro will then ignore the delta pressure and will continue flushing according to the set Time Between Flushing only, until the alarm is reset.

• Dwell Time Main [Value in range 00:00 or 99:59] – Define for what length of time the main filter valve must be activated before the filter back flushing cycle is started. This output is typically used to control a pressure-sustaining valve or to start a booster pump to build up pressure for the back flushing process.


After start up of an irrigation cycle automatic filter back flushing will not be possible until the Water Fill Up time in screen 3.3 ALARM DEFINITION has elapsed. This Water Fill Up time is applied after the start of each valve in the irrigation cycle.

4.2.1.8 COOLING Eight cooling programs are available with two programs (periods) in each program. The periods can be defined to overlap, thus creating dynamic cooling or humidification. Different temperature and humidity sensors can be connected to each program.

There are five cooling programs in the NMC Junior. There are a maximum of two temperature sensors and one humidity sensor.

The cooling/humidification program is used to keep the temperature below a set value and/or the humidity above a set value. Each program can be set to maintain temperature or humidity as its first priority. The status can be defined as cooling or humidification. The aim of the status field is to help the user to understand the process that should take place by placing the related set point first: 1) Above temperature when the status is cooling or 2) Below relative humidity when the status is humidification.

COOLING / HUMIDIFICATION PROGRAM • Program [Value in range 1 to 8] – Choose the required program 1 to 8, press ENTER to

confirm. • Status [Value in range Cooling or Humidification] – Define whether the programs first

priority is maintaining temperature or humidity. o Cooling – The programs first priority is to maintain set temperature. o Humidification – The programs first priority is to maintain set humidity level.

• Program Line 1 and 2 - Each cooling / humidification program has 2 program lines. A single line or both lines can be setup per program. When using both program lines there are two options for the program setup:

o Different time frames – Two different time frames can be defined, each with its own start (from) and end (to) times. Each time frame can be setup with its own temperature and humidity levels.

o Overlapping time frames – When overlapping time frames are setup for program lines 1 and 2 the program operation will be dynamic. The software will calculate and apply the on and off times between the programmed on and off times for the 2 program lines based on the measured temperature or humidity. This dynamic

JR


operation will be controlled by measured temperature for cooling or measured humidity level for humidification.

• From [Value in range 00:00 to 23:59] – Set the start time of the cooling / humidification program.

• To [Value in range 00:00 to 23:59] – Set the end time of the cooling / humidification program.

• For Status Cooling: o Above Temperature [Value in range 0 to 50] - Start cooling above this temperature.

Cooling will stop if the temperature drops below the set point minus internal dead-band of 0.5°C. For example: If set to 30°C cooling will start when the temperature is above 30°C and will stop when it drops below 29.5°C.

o Below Relative Humidity [Value in range 0 to 100] - Start cooling below this humidity. Cooling will be stopped when the humidity level reaches the set point plus internal dead-band of 2%. For example: If set to 80% cooling will stop when the humidity is above 82% and will be resumed when the humidity drops below 80%.

• For Status Humidification: o Below Relative Humidity [Value in range 0 to 100] - Start humidification below this

humidity. Humidification will stop if the humidity goes above the set point plus internal dead-band of 1%. For example: If set to 80% humidification will start when the humidity is below 80% and will stop when it is above 81%.

o Above Temperature [Value in range 0 to 50] – Start humidification above this temperature. Humidification will stop if the temperature drops below the set point minus the internal dead-band of 0.5°C. For example: If set to 25°C humidification will stop when the temperature drops below 24.5°C and will be resumed when it goes above 25°C.

• On [Value in range 00:00:00 to 99:59:59] – Define the on time of the cooling valve. If on time is set to 00:00:00 the cooling valve or group will not be activated. If more than one cooling valve or group is defined there will be no delay between the cooling valves or groups as they work sequentially (see Cool # below).

• Off [Value in range 00:00:00 to 99:59:59] – Define the off time of the cooling valve. If off time is set to 00:00:00 the cooling valve or group will be constantly on. The off time is applied from the last activated cooling valve or group in the sequence (see Cool # below).

• Cool # [Value in range 0 to 40, 10 cooling valves per program] - Assign cooling valves to this program. The assigned cooling valves will be operated sequentially. The number of cooling programs which can be operated simultaneously is defined in line Maximum Cooling Parallel which can be found in screen 6.2 SYSTEM SETUP.

• Temperature Sensor [Value in range 0 to 8] – Assign up to two temperature sensors per program.

• Humidity Sensors [Value in range 0 to 8] – Assign up to two humidity sensors per program.

The temperature and humidity values used by a cooling program will be an average of the readings from the sensors connected to that cooling program. If there is a malfunction in one of the sensors, a message will be displayed, and that sensor will be taken out of the average sensor calculation. If all the temperature or humidity sensors are out of order the cooling program will not operate.

NB


OPERATING A COOLING PROGRAM BY TIME ONLY No temperature or humidity sensors must be defined as analogue inputs in order for a cooling program to run only on time. Dynamic operation of cooling program is also not possible:

• Status can be set to cooling or humidification. • From (start) and To (end) times for cooling program must be set. • Set the Above temperature and Below relative humidity to 0. • Define the required On and Off times for the cooling valve or group. • Next to Cool # define the cooling valves numbers connected to the cooling program. • Do not define any temperature or humidity sensors for the cooling program.

Example: Cooling Program for greenhouse

FIGURE 60. COOLING PROGRAM IN GREENHOUSE EXAMPLE Dynamic cooling is required for the greenhouse from 08:00 to 16:00 for cooling valves 1 and 2. The valves on time is fixed on 10 seconds. At 25°C the valve off time must be 10sec and at 35°C the valve off time can be reduced to 5 seconds. Greenhouse humidity level cannot exceed 80%.

MISTING PROGRAM

• # [Value in range 1 to 40] - Misting program number. • Number [Value in range 1 to 40] – Assign a misting valve number to the program. It is

possible to associate the same misting valve to several programs. • Start [Value in range 00:00 to 23:59] – Set the start time of the misting program. If start time

is set to 00:00, it will automatically be changed to --:--, meaning the program is not operational.

• End [Value in range 00:00 to 23:59] – Set the end time of the misting program. The misting program will only be operational in the defined time window (between Start to End times). Each misting program can be operational on different hours.

• On [Value in range 00:00:00 to 99:59:59] – Define the on time of the misting valve. If on time is set to 00:00:00 the misting valve will not be opened.

• Off [Value in range 00:00:00 to 99:59:59] – Define the off time of the misting valve. If off time is set to 00:00:00 the misting valve will be constantly on.

The misting program table is sorted according to misting valve number as the first priority and start time as the second priority. The misting valves will always appear in groups with an increasing order so that the orientation is quick and easy. Each misting group has an inside start time sorting, misting valves with a later start is moved to the end of the group. If you delete a row (by zeroing the misting valve number) it will be moved to the end of the table and the rest of the rows will move one step up. Pressing the MENU key does this sorting.


When misting is on all related devices (misting valve, main valve and/or pump) are operational. When misting is off only the pump continues to operate.

Example: Misting Program for greenhouse

FIGURE 64. MISTING PROGRAM – GREENHOUSE EXAMPLE Misting valve 1 is required to cycle on and off from 08:00 to 16:00. On for 5 seconds and off for 2 minutes 30 seconds.

WATER HEATING

• From Time [Value in range 00:00 to 23:59] – Set the start time of the water heating program. • To Time [Value in range 00:00 to 23:59] – Set the end time of the water heating program. • Water Temperature [Value in range -20°C to 50°C] – Water heating will be activated when

the measured temperature drops below this value. • Difference [Value in range 0.3°C to 20°C] – Dead band for stopping water heating. When the

measured water temperature reaches the set water temperature + difference water heating will be stopped. For example: Water temperature is set at 25°C and the difference set at 2°C. Water heating will start when the temperature drops below 25°C and will stop when it is 27°C or above. The Minimum difference is 0.3°C and the default is 0.5°C.

• Temperature Sensor #1 / 2 [Value in range 0 to 8] – Assign up to 2 temperature sensors to the water heating program. If 2 sensors are assigned the water heating program will use the average reading between the sensors.


Example: Water Heating for frost control It is required from 04:00 until 07:00 every morning to activate the frost control system when the temperature drops below 2°C. Frost control can stop if the temperature increases to 5°C. Temperature sensors number 3 and 4 measures outside temperature.

ALARM DEFINITION

• Water Fill Up [Value in range 0 to 99] - Time for pipeline fill up. The system will ignore high flow and will not generate a high flow alarm during this period. This Water Fill Up time is applied after the start of each valve in the irrigation cycle.

• Water Leak [Value in range 0 to 9999.99] - Quantity of water that must be measured by the water meter, when an irrigation cycle is not active, that will trigger a water leak alarm.

• Water Leak Period [Value in range 00:00 to 23:59] - Time period to measure the water leak quantity above If it takes the system longer than indicated here, to measure the water leak quantity, the alarm will not be generated.

• *Identify Leak Subtracting Meter? [Value in range NO or YES] – Choose to identify or not identify a water leak from a subtracting water meter (relevant only when operating by water meter type water source in menu screen 7.5 WATER METER).

• Dosing Channel Leak Delay [Value in range 0 to 99] – Delay after dosing channels are stopped before the system starts measuring for dosing channel leaks. This feature is usually used to cope with problems regarding hydraulic pumps that work with dosing meters.

JR


• Dosing Channel Leak [Value in range 0 to 99] - Number of pulses measured from the dosing meter when the dosing channel should be idle before the system will generate a dosing leak alarm.

• *Dosing Flow Difference [Value in range 0 to 99] – Percentage difference from calculated dosing channel flow above or below which an alarm will be generated. For example: If the calculated dosing channel flow is 100l/h and the dosing flow difference of 25%, an alarm will be generated when the actual flow measured is less than 75l/h or above 125l/h.

• Missing Pulses For No Flow [Value in range 0 to 99] – Number of missing pulses from the water meter before the system will generate a no flow alarm. The system calculates the expected time between pulses from the set flow rate and the pulse rate of the water meter. If more time has passed than expected for the set number of missing pulses the system will generate a no flow alarm.

• Stop System Consecutive Flow Alarms [Value in range 0 to 99] – Number of consecutive flow alarms of the same type (high flow, low flow and no flow) from different valves or valve groups before the system is stopped. This setting is used to pause the system when there is a general malfunction that occurs in a few valves or valve groups.

• *Number of Irrigations Without Drainage [Value in range 0 to 99] – Number of irrigations given without measuring drainage, above which an alarm will be generated. This alarm usually indicates that the irrigation quantity is too small or that there is a malfunction in the drainage measurement.

• *Low Pressure Alarm [Value in range 0 to 10bar] – Define the minimum allowed irrigation system pressure under which an alarm will be generated.

• *Number of Short Circuits To Pause [Value in range 0 to 99] – Number of short circuit alarms detected before the system is paused. This setting is used to pause the system when a general malfunction occurs causing several outputs to short circuit.

• *Short Output Level [Value in range 0 or 60 to 350] – Set the threshold value to be considered as a short circuit (see setting short circuit threshold level below).

• The following parameters will be visible only if expansion boxes are defined: • *Short Output Level Expansion Box 1 [Value in range 0 or 60 to 350] - Set the threshold

value for expansion box 1 to be considered as a short circuit (see setting short circuit threshold level below).

• *Short Output Level Expansion Box 2 [Value in range 0 or 60 to 350] - Set the threshold value for expansion box 2 to be considered as a short circuit (see setting short circuit threshold level below).

• *Short Output Level Expansion Box 3 [Value in range 0 or 60 to 350] - Set the threshold value for expansion box 3 to be considered as a short circuit (see setting short circuit threshold level below).

*The NMC Junior does not feature these alarm definitions.

JR


Setting Short Circuit Threshold Level


• In menu screen 5.1 RELAYS manually operate the maximum amount of devices to be used simultaneously (maximum output load expected).

• Observe the value displayed to the right of the last line Load Output Level (A/D) in menu screen 5.1 RELAYS. Calculate the desired threshold level as follows:

TABLE 4. SHORT CIRCUIT THRESHOLD SET VALUES

Observed A/D level For set value Notes

0 to 60 Add 30 Do not set a value less than 60

60 to 300 Add 50% If upper limit of 350 is exceeded, use external power source

Above 300 Use external power source (consult Netafim technician)

• Use the calculated value to set the Short Output Level in menu screen 3.3 ALARM DEFINITION for the Local and Expansion Boxes if connected.

• To disable Short Output Level set the value to 0.

In addition to the list in FIGURE 80, the NMC Junior lists the following alarm definitions in Sub-menu 3.3 that are listed elsewhere, in Sub-menu 3.5 in the NMC Pro:

• Delta EC Low • Delta EC High • Delta pH Low • Delta pH High

when the channel/s are opened. o External Pause – The external pause alarm is used to pause the system through a

digital input. This alarm can be activated by any external digital sensor (flow no flow switch, pressure switch, etc.). The action applied from an external pause alarm to the irrigation and dosing processes cannot be changed from PAUSE IRRIGATION.

o *Dosing Booster Protection – This alarm is used to protect the dosing booster pump through a digital input. This alarm can be activated by any external digital sensor but normally a pressure switch is used.

o *Low Pressure – With pressure sensors (transducers) connected to the NMC Pro the irrigation system pressure can be monitored. In menu screen 3.3 ALARM DEFINITION line Low pressure Alarm (bar) the pressure value for this alarm can be set.

o Remote Unit Error – Error detected on single cable remote unit or radio unit. o Remote Unit Communication Failure – Communication failure with remote unit,

communication lost with single cable remote unit or radio unit.


• Irrigation and Dosing [Value in range STOP or CONTINUE] – Action applied to processes. o STOP – Stop irrigation and/or dosing for the current valve (or valve group) and

continue to the next valve (or valve group). o CONTINUE – Continue irrigation and/or dosing for the valve (or valve group) that

caused the alarm. This option means that the system will register an alarm but will not take action.

• Delay [Value in range 00:00 to 99:59] – Define the period that the failure must be active before the NMC Pro will register an alarm and take action.

• Alarm Active [Value in range No or Yes] – Define whether the alarm output should be triggered by the corresponding alarm.

An alarm will be generated on the NMC Pro even if the alarm settings are set to continue the process and/or the alarm output has been set to not active.

*The NMC Junior does not feature these alarm settings. In addition to the list in FIGURE 81, the NMC Junior lists the following alarm settings in Sub-menu 3.4 that are listed elsewhere, in Sub-menu 3.6 in the NMC Pro:

EC/pH ALARM DEFINITION

• *Delta EC Low [Value in range 0.2 to 99.0] – If the measured EC value is lower than the set value minus delta EC low the system will generate a Low EC Alarm.

• *Delta EC High [Value in range 0.2 to 99.0] – If the measured EC value is higher than the set value plus delta EC high the system will generate a High EC Alarm.

• *Delta pH Low [Value in range 0.2 to 99.0] – If the measured pH value is lower than the set value minus delta pH low the system will generate a Low pH Alarm.

• *Delta pH High [Value in range 0.2 to 99.0] – If the measured pH value is higher than the set value plus delta pH high the system will generate a High pH Alarm.

• Delta EC Pre-Control Low [Value in range 0.2 to 99.0] – If the measured EC pre-control value is lower than the set value minus delta EC pre-control low the system will generate a Low EC Pre-Control Alarm.

• Delta EC Pre-Control High [Value in range 0.2 to 99.0] – If the measured EC pre-control value is higher than the set value plus delta EC pre-control high the system will generate a High EC Pre-Control Alarm.

• Emergency EC High (1 Minute Delay) [Value in range 0 to 99.0] – If the measured EC is higher than the value set here for more than 1 minute the system will be stopped. This setting should be used to protect the plants and should generally be higher than the EC high alarm.

• Emergency pH Low (1 Minute Delay) [Value in range 0 to 99.0] – If the measured pH is lower than the value set here for more than 1 minute the system will be stopped. This setting should be used to protect the plants and should generally be lower than the pH Low alarm.
